I'll have to take a look. It depends on whether base64 is specified as an octet-stream to Unicode stream transformation or as an embedding of an intermediate representation into Unicode. Granted, defining the base64 alphabet as a subset of Unicode seems like the logical way to do it in the context of XML.
Please do take a look. It is the only way: If you were to embed base64 bytes into character data content of an XML element, the resulting XML file might not be well-formed anymore (if the encoding of the XML file is not an ASCII superencoding).
Regards, Martin
